Unravelling the structural origin of cyclic fatigue in ferroelectrics. Ferroelectric materials have extensive applications in electromechanical devices and memories and in service are often subjected to repeat mechanical and/or electrical loading, leading to cyclic fatigue and failure. This project aims to apply in-situ electron microscopy techniques and computational modelling to explore cyclic ferroelectric fatigue behaviour and to understand the relationships between local atomic scale struct ....Unravelling the structural origin of cyclic fatigue in ferroelectrics. Ferroelectric materials have extensive applications in electromechanical devices and memories and in service are often subjected to repeat mechanical and/or electrical loading, leading to cyclic fatigue and failure. This project aims to apply in-situ electron microscopy techniques and computational modelling to explore cyclic ferroelectric fatigue behaviour and to understand the relationships between local atomic scale structure and fatigue. The structural origin of ferroelectric fatigue has not been clear because of the limitations of previous measurement capabilities. This project will provide guidance in materials design to increase ferroelectric fatigue lifetime for more reliable ferroelectric-based electronic devices.Read moreRead less
Low-density high-performance proppants for hydraulic fracturing process . Australia has vast resources of unconventional oil/gas, which require hydraulic fracturing to stimulate production.

Australia has vast resources of unconventional oil/gas, which require hydraulic fracturing to stimulate production. This project aims to develop advanced low-density high-performance proppants from industry waste for hydraulic fracturing. This will be achieved by selecting purer SiO2 raw material, carefully designing the porous structure, and fully understanding its relationship with strength and pack conductivity. Low-density means no chemicals in proppant transportation and application. Successful development of such high-performance proppants will significantly increase Australia oil/gas exploration and production with an environmental acceptable technology, a leap forward for the oil/gas industry in Australia and the world.Read moreRead less
